23 Claims.

This invention relates to linecasting and composing machines andparticularly to the shifting of the magazines of multi-magazinecomposing -machines by an automatically controlled unit responsive toprearranged signals.

For convenience in describing the present invention, the standardstructure of a well-known commercial linecasting and composing machine,

1 as illustrated in the accompanying drawing, will be referred tohereinafter as the principal machine, while the mechanism which isoperative for initiating the magazine shifting function of the principalmachine will be referred to here- -inafter as the control unit.

An object of the invention is to provide control means responsive toselectable elements under the control of stored signals for the magazineshifting mechanism of standard linecasting machines.

The invention features an arrangement for rendering the control unitnon-responsive to repeated identical magazine shift signals.

In multiple magazine linecasting machines any one of the two or morematrix storage magazines may be rendered capable of delivering matricesby establishing operative relation between the magazine and a set ofmatrix selecting lever systems. Such establishment of relationship maybe described as qualifying the magazine for operation, since there isconferred upon the magazine a quality which enables it to perform thefunction for which it is provided, namely, to discharge matrices.

Briefly, the invention includes mechanical means for depressing themagazine shift key of a standard commercial linecasting and composingmachine and thereby automatically starting into operation a. magazineshifting mechanism of the linecasting machine. When the magazine shiftoperation has been substantially completed, the shift key is permittedto return to its unoperated position and the control unit is renderedunable to respond to a like magazine shift signal. A different magazineshift signal will then be effective upon the control unit to effect thedepression of the magazine shift key to operate the magazine shiftingmechanism whereby the magazines are restored to their previous operativecondition. Thus successive different shift signals will alternativelycondition the magazines, but successive identical magazine shift signalswill not operate the magazine shifting key.

For a complete understanding of the invention, reference may be hadtothe following description and to the accompanying drawing in which thesingle figure represents schematically in perspective a control unithaving embodied therein the subject matter of the invention as appliedto the magazine shifting mechanism of a standard commercial linecastingmachine.

In the drawing, only so much of the mechanism of the principal machinehas been shown as isdeemed necessary to disclose clearly the cooperationof the control unit therewith. For a full and complete understanding ofone form of 1 selecting means which may be employed for initiating theoperation of the control unit which forms the subject matter of thisinvention, reference may be had to Patent No. 2,036,282, granted April7, 1936 to E. S. Larson.

Principal machine Referring now to the drawing, the reference numeral l0designates a pair of matrix storage magazines of a standard commerciallinecasting and composing machine. The magazines may be supported at therear edges thereof by pivots (not shown) and the upper magazine may besupported above the lower magazine in the usual way so that the twomagazines may be shifted as a unit. A bracket H, having a downwardlyextending arm 12, is provided for supporting the magazines adjacent thefront edges thereof and at the lower end of the arm I2 is secured atransversely extending pivot pin l3. A toggle lever system consisting ofthe levers I 4 and I6 connects the bracket H to a portion I! of thestationary frame of the linecasting machine, there being a pivot pin I8secured to the frame portion I! for pivotally securing the lower end ofthe lever 16. The upper end of the lever l4 pivotally engages the pivotpin l3, and the adjacent ends of the levers I4 and I5 are pivotallyconnected together by the common pivot 19 which has an extensionslidable in a slot 2! in the frame portion I! for guiding and limitingthe movement of the toggle lever system,

A bell crank lever 22, which is pivotally mounted on a fixed pivot 23,has one end operatively engaging the pivot pin Hi to operate the toggle5 lever system and has its other end connected by a link 24 to a crankpin (not shown) carried by a rotatable cam member 26. The rotatablemember 25 is fixed to a rotatable shaft 21 which is driven through themedium of bevel gears 28 and 29, shaft 3|, and friction clutch 32, froma worm gear 33 to which rotation may be imparted by a worm 34. The worm34 is loosely mounted on a shaft 36, which may be any power driven shaftof the principal machine such as the socalled intermediate shaft. Theloose mounting of the worm 3% permits the shaft 36 to rotateindependently of the worm, and the shaft has secured thereto in spacedrelation to the worm 3d a bevel gear 31.

A clutch sleeve 38 is loosely and slidably mounted on the shaft 35intermediate the worm 34 and the gear 37 and the sleeve 38 has positivedriving connection with the worm 34 through the medium of leftwardlyextending fingers 39, which are disposed within slots 4| in the hub ofthe worm 54. At its opposite end, the sleeve 38 is provided with teeth42 which may be brought into engagement with recesses 43 formed in thehub of beveled gear 31 to permit the establishment of driving connectionbetween the beveled gear 3? and the worm 34 when the clutch sleeve 33 isshifted rightwardly. The sides of the teeth 52 are preferably disposedobliquely with respect to the faces thereof and the recesses :13 arecorrespondingly formed, as shown in the drawing, so

that when the clutch sleeve is brought into en-,

gagement with the hub of the rotating bevelled gear 37, a mutual cammingaction between the teeth 42 vand recesses 43 creates a continuingtendency for the clutch sleeve to be forced out push rod 52 by means ofthe pivot pin 55.

of engagement. Thus the clutch always seeks disengagement unlessrestrained therefrom, and means, presently to be described, is providedfor so restraining the clutch during intervals in which its continuedengagement is desired.

A clutch yoke 44 engages the clutch sleeve 38 and isconnected toa lever45 mounted on a rock shaft 4? by means of a pin 48. At the opposite endof the rock shaft 41 from the lever 45 there is secured a lever 49 whichhas pivotally depending from the outer end thereof a link 5!. A push rod52 is positioned below and in alignment with the link 5|, .and akeylever 53 which is pivotally supported at 54 pivotally engages the Thekeylever 53 is provided with a finger key 55.

In order to insure the completion of a magazine shift after it has beeninitiated, the rotatable cam member 25 which operates the link 24 isprovided on its opposite face with diametrically opposed recesses 51. Alever 58, pivotally mounted at 55, has one end thereof engaging theclutch yoke 35 and the other end terminating in a portion 5! which mayenter a recess 51.

The operation of the disclosed part of the principal machine is asfollows: When the magazines are to be shifted, the finger key 55 is depressed, which causes the keylever 53 to rock on the pivot 55 and raisethe push rod 52 upwardly. The push rod 52 reciprocates the link 5!, thusrotating the lever 49 and rocking the shaft 47 to cause the teeth 42 onthe clutch sleeve 38 to engage the hub of the continuously rotatedbeveled gear 3?, and thus drive the worm 3 5,

The rotation of the latter causes the worm gear 33 to be driven andthrough the medium of elements previously described the member 26 isrotated and the link 25 is thereby caused to rotate the bell crank lever22. The bell crank lever 22 may be rotated counterclockwise from theposltion shown in the drawing and this causes the pivot pin Hi to travelto the opposite end of the guide slot 2i and rotates the lever l6counterclockwise onits pivot pin 18 to lower the magazines 55 by drawingdownwardly on the lever It.

Since the lever 58 is connected to the clutch yoke l i, the shifting ofthe clutch yoke to cause engagement of the clutch results in a counterclockwise rotation of the lever 58 about the pivot 59. This rotation ofthe lever 58 causes the portion Bl of the lever to be withdrawn from arecess 5| in the face of the rotatable cam 26. As cam 26 rotates, thelever 58 is blocked from clockwise rotation by the engagement of theportion 5i of the lever with the face of cam 26. When cam 26 hascompleted one-half revolution, which occurs at the completion of amagazine shift, a recess 51 is brought into alignment with the portion6! of the lever 58, so that that portion may enter the recess, thuspermitting the clutch to become disengaged by a leftward movement of theclutch sleeve 38 under the influence of the mutual camming action of theteeth 42 and recesses 53. a

Control unit The reference numeral 52 designates a set of code barswhich are adapted to selectively condition the code levers 63 and 64.The code bars are responsive to stored signals in a manner fullydescribed in the above identified patent, and a complete understandingof the manner in which the selective conditioning of the selectablecodelevers 53 and 65 is accomplished may be ob-' It is deemed tained byreference to the patent. sufficient to state here that the code bars 62are capable of a slight endwise reciprocatory motion' and that theselective conditioning of the code levers 83 and 6d occurswhen the codebars 52 assume certain predetermined positions.

l vers 53 and 64, it is reciprocated rightwardly by a functionperforming bail not shown.

Levers 66 and 5'! pivoted at 68 engage the code levers 53 and 54respectively, so that upon the rightward reciprocation of one of thecode levers,

its cooperating lever 66 or 67 is rotated in a clockwise direction. Thelevers 66 and 6'? are normally urged in a counterclockwise direction bythe springs 69 and H3 respectively.

Adjacent to the left-hand end of the levers 66 and 51, a T-shaped memberH which has slots 12 in the shank portion thereof is slidably mountedupon the fixed pins 73.

75 of a lever Ti. The lever 71 is fixed to a shaft 18 which may bejournalled in any convenient fixed portion of the principal machine andwhich has secured to its opposite end a lever 19 which: is provided atits forward end with a downwardly extending portion 8|, the lower end ofwhich is disposed in alignment with and preferably a small distanceabove the finger key 55. Adjacent to the lower end of the lever H is abell crank lever 82 which constitutes a latch andv The bell crank lever82.

wise direction, and a spring 88 urges the member H rightwardly, thesprings 87 and 88 normally maintaining the end 8| of lever 79 fromoperative engagement with the finger key 55.

The arms of the T-shaped lever H are provided with slots 91 in which aredisposed pins 92 carried by a reciprocable member 93. The member 93 isthus supported by the T-shaped lever H and is provided with rightwardlyex- Upon the selective conditioning of either of the code At thelefthand end of the shank of the member 1| is: mounted a pin l' which isdisposed within a slot A spring 86 urges the bell.

tending portions 94 which are spaced apart a distance different from thedistance between the left-hand ends of the levers 66 and 61, so that oneof the projections 94 may be aligned with the end of one of the leversB6 and 61 in each of the limiting positions of the reciprocable member92, as determined by the slots 9|. A lever 95 which is pivoted at thefixed point 96, has one end pivotally engaging the reciprocable member93 at 97 and the other end pivoted at 98 to a link bar 99 which ispivotally associated with the magazines II] to be moved upwardly ordownwardly as the magazines are so moved. The link bar 99 is providedwith a hump or cam portion 10! and the upper end of the bell crank leveror latch 82 is provided with a cam projection I02 disposed in the pathof the cam portion ll of the link bar 99.

The operation of the control unit is as follows: Since the lower portion94 of the reciprocable member 93 is in alignment with the left-hand endof lever 56, it will be assumed that a predetermined stored signal-hasactuated the code bars 92 to condition selectively the code lever 99.The rightward movement of the code lever 33 under the influence of anoperating bail (not shown), will cause the lever 66 to be rotatedclockwise and its left-hand end will move leftwardly the lower element94 of the reciprocable member 93 which, by reason of the disposition ofthe pins 92 in the slots 9|, will cause the T- shaped member H to slideleftwardly upon the pins 13. The pin and slot connection of the memberll with the lever 11 will cause the latter to be rocked clockwise, andas the lower end of the lever ll moves behind the shoulder 84 of thelatch 32, the latter will be rocked counterclockwise by its spring 86 toretain the lever 11 in the position into which it has been rotated. Therotation of the lever H causes the shaft 18 to rock in clockwisedirection, which carries the end 9! of the lever 79 into engagement withthe finger key 55 and causes the depression of the finger key and thusthe actuation of the keylever 53. The actuation of the keylever 53 willcause the magazine shifting mechanism of the principal machine tooperate in the manner previously described. Since the magazines havebeen shown in their uppermost position, the operation of the magazineshifting mechanism in response to the selective conditioning of the codelever 69 will cause the magazines to be lowered to their lowermostposition.

The downward movement of the magazines causes the link bar 99 to bemoved downwardly, and an upward movement is transmitted to thereciprocable member 93 through the agency of the lever 95. As thereciprocable member 93 moves upwardly, the lower projection 94 is movedout of alignment with the lever 66 and the upper projection 94 is movedinto alignment with the end of lever 61. It is apparent from thisdescription that should the code lever 63 again be selectivelyconditioned in response to a re peated signal, the magazine shiftingmechanism would not be affected, for the reason that the lowerprojection 94 of the member 93 would be out of operative alignment withthe lever 66. This arrangement prevents the magazine shifting mechanismfrom responding to repeated identical magazine shifting signals andinsures the alternative conditioning of the magazines in response to theproper predetermined signals only.

The restoration of the magazines to the position shown in the drawing,after a shift operation as described in the foregoing paragraphs, isaccomplished by causing the code lever 64 to be selectively conditionedin response to a predetermined signal which differs from the signal towhich the code lever 63 is responsive. The selective conditioning of thecode lever 64 results in a clockwise rotation of the lever 61, which,through the operative alignment of the upper projection 94 therewith,will cause the T- shaped member H to slide upon the pins 13, thusrotating the lever 11, shaft 18 and lever '19 to effect the depressionof the keylever 53. The depression of the keylever 53 causes themagazine shifting mechanism of the principal machine to operate in themanner previously described, whereby the cam member 25 is rotatedthrough one-half revolution to rotate the bell crank lever 22 clockwiseby means of the link 24 and thus the magazines ID are returned to theiruppermost position.

The upward movement of the magazines is accompanied by an upwardmovement of the link bar 99, and a clockwise movement of the lever 95.The member 93 is moved downwardly upon the clockwise movement of thelever 95, bringing the lower projection 94 into alignment with the lever96 and withdrawing the upper projection 94 from alignment with the lever61.

In addition to shifting the reciprocable member 93 as outlined in thepreceding paragraph, the downward or upward movement of the link bar 99causes a clockwise rotation of the latch 82 by reason of the engagementof the cam portion I91 with the portion I02 at the upper end of thelatch 82. Upon the clockwise rotation of the latch 82, the lever I? isreleased from engagement with the shoulder 84 thereof and is enabled torespond to its spring 81 to rotate counterclockwise and thus release thefinger key 55. The spring 88 cooperates with the spring 8'! in releasingthe lever H, and the springs also cooperate in returning the T-shapedlever H to its normal or inoperated position.

Although a particular embodiment of the invention has been shown in thedrawing and described in the specification, it is to be understood thatthe invention is not limited to the specific structure disclosed, butthat it is capable of modification, rearrangement, or substitution ofelements and operations without departing from the spirit of theinvention and within the scope of the appended claims.
